The theft behavior sensing device senses a theft behavior to the vehicle. The window display device has a display region on a window of the vehicle for displaying indication. The display controlling device controls the indication, which is displayed by the window display device, when the theft behavior sensing device senses the theft behavior.
The invention, together with additional objectives, features and advantages thereof, will be best understood from the following description, the appended claims and the accompanying drawings in which:
The first embodiment of the present invention will be described with reference to accompanying drawings. As shown in FIG. 1A , a vehicle antitheft apparatus of the present embodiment includes a theft sensing device (theft behavior sensing device) 100 and an injecting device 150. The theft sensing device 100 senses a theft behavior to a vehicle (a behavior to steal the vehicle), and outputs a sensing result to the injecting device 150. Then, the injecting device 150 operates based on the sensing result.
The intrusion sensor 120 senses an intrusion into a cabin of the vehicle, and also senses a person, who approaches to the vehicle, for example, to try to intrude into the vehicle. Specifically, for example, an image captured by a capturing device (photographing device), such as a camera, may be analyzed to sense the intrusion into the vehicle cabin or the person approaching the vehicle. Also, a transmitted wave is transmitted to an interior and an exterior of the vehicle, and a reflected wave of the transmitted wave is used to sense the intrusion into the vehicle cabin or the person approaching the vehicle.
The vibration sensor 130 senses each vibration of the vehicle in a fore-aft direction, a right-left direction, and an up-down direction. For example, an acceleration sensor may be used for the vibration sensor 130. The theft determining device 140 senses the theft behavior of the vehicle. Typically, the theft determining device 140 senses the theft behavior by integrating the sensing results from the tilt sensor 110, the intrusion sensor 120, and the vibration sensor 130. When the theft determining device 140 senses the theft behavior, the theft determining device 140 outputs a sensing result, which indicates that the theft behavior is sensed, to the injecting device 150.
The injecting device 150 includes a paint tank 150 a, an injection controlling device 150 b, and a nozzle 150 c. The paint tank 150 a is a container storing a paint that is injected through the nozzle 150 c. The paint may preferably include fluorescent paint or luminous paint, which irradiates ultraviolet rays to be luminous. This makes is easier to identify the person who conducts the theft behavior at night.
The injection controlling device 150 b controls an operation such that the paint in the paint tank 150 a is injected through the nozzle 150 c when the sensing result of the theft determining device 140 indicates that the theft behavior is sensed. The nozzle 150 c is a nozzle, through which the paint is injected, and the nozzle 150 c is mounted to a blind spot, which is not seen from the person conducting the theft behavior. The blind spot may include an interior of a wheelhouse and a lower portion of a door. The person who conducted the theft behavior may be seated or try to be seated in a driver's seat of the vehicle without recognizing the nozzle 150 c. Thus, by using the above nozzle 150 c, the paint may be reliably injected toward the person (intruder).
Next, an operation of the vehicle antitheft apparatus will be described with reference to a flow chart shown in FIG. 1C . Firstly, at step S110, the sensing of the theft behavior is started (i.e., security system is started). At step S120, the vehicle antitheft apparatus is kept on a standby for a predetermined interval. When the predetermined interval has passed, it is determined at step S130 whether the theft behavior is sensed or not. When the theft behavior is not sensed (determining result is NO), control continues with step S120 to repeat the above process.
When the theft behavior is sensed (the determining result is YES), control continues with step S140, at which the injecting device 150 is operated (started). Then, at step S150, the paint is injected through the nozzle 150 c.
As discussed above, the vehicle antitheft apparatus of the present embodiment injects the paint toward the interior and the exterior of the vehicle cabin when the theft behavior is sensed.
Thus, someone, who receives the injection of the paint, can be effectively identified as the person, who conducted the theft behavior. This may effectively discourage a person from conducting the theft behavior.
Modification of the present embodiment will be described. The paint injected through the nozzle 150 c may be attached to a body of the vehicle in addition to the person who conducted the theft behavior. Therefore, a device for easily removing the attached paint may be preferably provided.
The second embodiment of the present invention will be described with reference to accompanying drawings. Similar components of a vehicle antitheft apparatus of the present embodiment, which are similar to the components of the vehicle antitheft apparatus of the first embodiment, will be indicated by the same numerals. Also, explanation of the common point will be omitted and a different point from the first embodiment will be mainly described. As shown in FIG. 2A , the vehicle antitheft apparatus of the present embodiment includes the theft sensing device 100 and an oil pressure controlling device 160.
The theft sensing device 100 senses the theft behavior to the vehicle, and outputs the sensing result to the oil pressure controlling device 160. Then, the oil pressure controlling device 160 operates based on the sensing result. FIG. 2B shows a structure of the theft sensing device 100 and the oil pressure controlling device 160. The structure of the theft sensing device 100 is similar to that of the first embodiment.
The oil pressure controlling device 160 controls a suspension stroke (e.g., stroke height of a suspension) of the vehicle using an oil pressure. Thus, in a case where a controlling device for controlling the suspension stroke using the oil pressure (air pressure) is installed in the vehicle as above, the vehicle can be vibrated by using the controlling device.
The oil pressure controlling device 160 controls at least the suspension stroke for a front wheel on a driver's seat side of the vehicle to vibrate the vehicle when the sensing result of the theft determining device 140 indicates that the theft behavior is sensed. The theft person (e.g., thief), who conducts the theft behavior, is likely to firstly intrude into the driver's seat when the person intrude into the vehicle cabin. Therefore, by controlling the suspension stroke of the front wheel on the driver's seat side of the vehicle, psychological warning can be effectively provided to the theft person.
Next, an operation of the vehicle antitheft apparatus will be described with reference to a flow chart shown in FIG. 2C . Operations at step S110 to step S130 are similar to those in the first embodiment. When the theft behavior is sensed at step S130, the oil pressure controlling device 160 is operated (started) at step S140 a, and the vehicle is vibrated at step S150 a. The vibration of the vehicle body may be continued for a predetermined time such that a continuous psychological warning can be given to the theft person.
As discussed above, in the vehicle antitheft apparatus of the present embodiment, when the theft behavior is sensed, the vehicle is vibrated. Therefore, the psychological warning is given to the theft person. This may effectively discourage the person from conducting the theft behavior.
The third embodiment of the present invention will be described with reference to accompanying drawings. Similar components of a vehicle antitheft apparatus of the present embodiment, which are similar to the components of the vehicle antitheft apparatus of the first and second embodiments, will be indicated by the same numerals. Also, explanation of the common point will be omitted and a different point from the embodiments will be mainly described. As shown in FIG. 3A , the vehicle antitheft apparatus of the present embodiment includes the theft sensing device 100 and a smoke generation controlling device 170.
The theft sensing device 100 senses the theft behavior to the vehicle, and outputs the sensing result to the smoke generation controlling device 170. Then, the smoke generation controlling device 170 operates based on the sensing result. FIG. 3B shows a structure of the theft sensing device 100 and the smoke generation controlling device 170. The structure of the theft sensing device 100 is similar to that of each of the first and second embodiments.
The smoke generation controlling device 170 injects smoke toward the theft person, who is seated or tries to be seated in the driver's seat of the vehicle, when the sensing result of the theft determining device 140 indicates that the theft behavior is sensed. Thus, the injection of the smoke intimidates the theft person.
Next, an operation of the vehicle antitheft apparatus will be described with reference to a flow chart shown in FIG. 3C . Operations at step S110 to step S130 are similar to those in the first and second embodiments. When the theft behavior is sensed at step S130, the smoke generation controlling device 170 is operated (started) at step S140 b, and the smoke is generated at step S150 b. The smoke may be preferably generated for a predetermined period until the vehicle cabin is filled with the smoke. This may make it impossible for the theft person to reliably have a full view of the exterior of the vehicle from the driver's seat. Thus, this may discourage the theft person from stealing the vehicle.
As discussed above, in the vehicle antitheft apparatus of the present embodiment, when the theft behavior is sensed, the smoke is generated toward the interior and the exterior of the vehicle cabin. By generating the smoke outside of the vehicle, the sensing of the theft behavior can be recognized even at a location far away from the vehicle. Thus, this may effectively discourage the person from conducting the theft behavior. Also, the generation of the smoke inside the vehicle cabin may disable the theft person in the driver's seat to reliably have the full view of the exterior of the vehicle. Thus, this may discourage the theft person from stealing the vehicle.
The fourth embodiment of the present invention will be described with reference to accompanying drawings. Similar components of a vehicle antitheft apparatus of the present embodiment, which are similar to the components of the vehicle antitheft apparatus of the first to third embodiments, will be indicated by the same numerals. Also, explanation of the common point will be omitted and a different point from the above embodiments will be mainly described. As shown in FIGS. 4A and 4B , the vehicle antitheft apparatus of the present embodiment includes the theft sensing device 100, shutters 180 a, 180 b, and a shutter controlling device 190.
The theft sensing device 100 senses the theft behavior to the vehicle, and outputs the sensing result to the shutter controlling device 190. Then, the shutter controlling device 190 operates the shutters 180 a, 180 b based on the sensing result. FIG. 4B shows a structure of the theft sensing device 100 and the shutter controlling device 190. The structure of the theft sensing device 100 is similar to that of each of the first to third embodiments.
The shutter 180 a, 180 b is provided to each wheel of the vehicle, and is controlled to move vertically by the shutter controlling device 190. The shutter controlling device 190 operates the shutters 180 a, 180 b for limiting an object from intruding (entering) into a clearance between the vehicle and a ground when the sensing result of the theft determining device 140 indicates that the theft behavior is sensed. This limits a jack up behavior (behavior to jack up the vehicle).
Next, an operation of the vehicle antitheft apparatus will be described with reference to a flow chart shown in FIG. 4C . Operations at step S110 to step S130 are similar to those in the first to third embodiments. When the theft behavior is sensed at step S130, the shutters 180 a, 180 b are displaced in a downward direction of the vehicle at step S140 c. This limits the object from entering into the clearance between the vehicle and the ground.
As discussed above, in the vehicle antitheft apparatus of the present embodiment, when the theft behavior is sensed, the shutters 180 a, 180 b are operated for limiting the jack up of the vehicle. Due to this, the vehicle is limited from being towed. Thus, this may effectively discourage the person from stealing the vehicle.
A modification of the present embodiment will be described. For example, when the controlling device for controlling the suspension stroke by using the oil pressure or the air pressure is mounted to the vehicle, the stroke may be adjusted such that a minimum ground clearance of the vehicle is equal to or less than a predetermined elevation when the theft behavior is sensed. For example, the minimum ground clearance of the vehicle may be made so small that the vehicle cannot be jacked up. Then, the theft person, which is conducting the theft behavior, is discouraged from towing the vehicle.
The fifth embodiment of the present invention will be described with reference to accompanying drawings. Similar components of a vehicle antitheft apparatus of the present embodiment, which are similar to the components of the vehicle antitheft apparatus of the first embodiment, will be indicated by the same numerals. Also, explanation of the common point will be omitted and a different point from the first embodiment will be mainly described. As shown in FIGS. 5A and 5B , the vehicle antitheft apparatus of the present embodiment includes the theft sensing device 100, a marking device 200, and a speed sensor 210.
The theft sensing device 100 senses the theft behavior of the vehicle, and outputs the sensing result to the marking device 200. Then, the marking device 200 operates based on the sensing result. FIG. 5B shows a structure of the theft sensing device 100 and the marking device 200. The structure of the theft sensing device 100 is similar to that of the first embodiment.
The speed sensor 210 senses a speed of the vehicle, and outputs a sensing result to the marking device 200. The marking device 200 includes a paint tank 200 a, a drop controlling device 200 b, a drop nozzle 200 c. The paint tank 200 a stores paint that is dropped (injected) through the drop nozzle 200 c. The paint may preferably include fluorescent paint or luminous paint, which irradiates ultraviolet rays to be luminous.
The drop controlling device 200 b operates such that the paint in the paint tank 200 a is dropped (injected) through the drop nozzle 200 c when the sensing result of the theft determining device 140 indicates that the theft behavior is sensed, and also when the speed is equal to or more than a predetermined speed. For example, the drop nozzle 200 c drops (injects) the paint, and a drop hole (injection hole) of the nozzle 200 c faces a road surface (ground).
Next, an operation of the vehicle antitheft apparatus will be described with reference to a flow chart shown in FIG. 5C . Operations at step S110 to step S120 are similar to those in the first embodiment. At step S130 d, it is determined whether the theft behavior is sensed and also whether the vehicle moves at a speed equal to or more than the predetermined speed or not. When a determining result is NO, process continues with step S120 to repeat the above process.
In contrast, when the determining result is YES at step 130 d, control continues with step S140 d, at which the drop controlling device 200 b is operated (started). At step S150 d, the paint is dropped (injected) through the drop nozzle 200 c. The paint may be preferably dropped at a predetermine interval such that the paint in the paint tank 200 a does not run out within a short period of time. Also, when the vehicle stops, the paint may preferably not be continuously dropped.
As discussed above, the vehicle antitheft apparatus of the present embodiment drops (injects) the paint toward the road surface when the theft behavior is sensed and the vehicle speed is equal to or more than the predetermined speed. Therefore, even when the vehicle is stolen, an escape route can be recognized based on the paint attached on the road surface. As a result, the vehicle may be effectively recovered.
The sixth embodiment of the present invention will be described with reference to accompanying drawings. Similar components of a vehicle antitheft apparatus of the present embodiment, which are similar to the components of the vehicle antitheft apparatus of the first to fifth embodiments, will be indicated by the same numerals. Also, explanation of the common point will be omitted and a different point from the embodiments will be mainly described. As shown in FIGS. 6A and 6B , the vehicle antitheft apparatus of the present embodiment includes the theft sensing device 100, the display controlling device 220, and a window display device 230.
The theft sensing device 100 senses the theft behavior to the vehicle, and outputs the sensing result to the display controlling device 220. Then, the display controlling device 220 controls indication of the window display device 230 (indication displayed by the window display device 230) based on the sensing result. As shown in FIG. 6B , the structure of the theft sensing device 100 is similar to that of each of the first to fifth embodiments.
The window display device 230 includes display regions located at a windshield, side windows, and a rear window. The indication displayed in the display regions is controlled by the display controlling device 220. The display controlling device 220 controls an operation, in which the window display device 230 displays that the vehicle is stolen (e.g., Now being Stolen), when the sensing result of the theft determining device 140 indicates that the theft behavior is sensed. Thus, a third party may be notified that the theft behavior is conducted.
Next, an operation of the vehicle antitheft apparatus will be described with reference to a flow chart shown in FIG. 6C . Operations at step S110 to step S130 are similar to those in the first embodiment. At step S115, the window display device 230 displays the indication of “on guard” and the like. When the theft behavior is sensed at step S130, the window display device 230 displays the indication of “Now being Stolen” and the like at step S140 e. Alternatively, the indication of the “Now being Stolen” may be irreversibly displayed by the window display device 230 using paint. Thus, in one embodiment, because the indication of “Now being Stolen” may be drawn in the display region on the window by the paint, the indication may not be disappeared easily.
Thus, the vehicle antitheft apparatus of the present embodiment controls the indication displayed by the window display device 230 when the theft behavior is sensed. This makes it possible to forcibly make the theft person recognize that an antitheft function of the vehicle is operated.
A modification of the present embodiment will be described. In the vehicle antitheft apparatus of the present embodiment, the indication displayed by the window display device 230 on the windshield (front window) may be alternatively controlled such that a light transmission of the windshield of the vehicle may be controlled to be equal to or less than a predetermined light transmission. This can obstruct a front view observed from the driver's seat. Thus, this may effectively discourage the person from stealing the vehicle.
Additional advantages and modifications will readily occur to those skilled in the art. The invention in its broader terms is therefore not limited to the specific details, representative apparatus, and illustrative examples shown and described.
